WAVE-MOTOR.

sci-m1 No. 787,922.

To all whom it may concern:

Be it known that I, ERIK ANDERSON, acitizen oi the United States, residing at San Francisco, in the county of San Francisco and State of Californian, have invented new by the waves, the power generating mecha-' nism carried by the buoyant member embodying a novel arrangement and construe tion of pistonswhich act to compress air, the air being conducted into a suitable tank or reservoir from which it-may be delivered through a pipe or conduit to the shore or other point where it is utilized as a motive agent.

With the above and other objects in View, the invention consists in the construction, combination and arrangement of parts, as will hereinafter be more fully described, illustrated and claimed. 1

In the accompanying drawing:-[*igure l is! a side elevation of a wave motor embodying the present invention showing the same suitably anchored. Fig. 2 is a side elevation of-the wave motor on an enlarged scale with the hood removed. Fig. 3 is an end elevation of the same. Fig. 4 is a plan view thereof.: Fig. 5 is a vertical diamet'rieal section taken in line with one of the piston shafts. Fig. 6 is a detail vertical section on the line ii-6 of Fig. 4.

The wave motor contemplated in this invention comprises a floating member 1 which is shown in the form of a barge or lighter of suitable size to support the air compressing mechanism hereinafter particularly de scribed, the said buoyant member or float 1 being designed to be anchored adjacent to the shore. the anchoring means being shown conveniently as consisting of a plurality of anchors 2 connected by chains 3 to the membeer 1. It will be noted that the member 1 is preferably anchored so that its length is arranged transversely to the incoming waves, whereby a longitudinal oscillatory move ment is imparted by the waves to the mem her 1.

Arranged at. the front and rear of the buoyant member are vertically extending sba't'ts 4 each of which carries a. duplex piston designated generally by the letter A. Each piston comprises a pair of concaveconvex piston heads 5 and 6 disposed reversely to each other or arranged with their convex sides toward each other as clearly shown in the drawings, the convex faces of the piston heads being connected by an annular wall or rim 7 formingvan air-tight buoyant chamber 8 of snilicient size to compensate for the weight of the duplex piston thereby enabLing said piston to operate easily. Theshaft 4 extends a suitable distance below the bottom piston head (3 and has radiating therefrom a series of stays 8 which are connected at their outer .and upper extremities to the lower piston head 6, a corresponding series of stays 9 connecting the upper piston head 5 with the shaft 4. as shown. the two heads of the piston thus being firmly braced relatively to the shaft 4.

Each shaft 4 is slidable longitudinally in a vertical direction through a tube 10 ex tending from the bottom to the top of the member 1 said tube being ater-tight to prevent leakage of water to the interior of the member 1. The shaft also extends considerably above the deck oi the member 1. where it passes through a combined guide and longitudinal truss 11 which also forms one of the supports -for a hood 12 shown in Fig. 1. the said hood resting at its bottom edge upon the deck 13 and being provided with any suitable number of ports or win- .dows 14. In addition to the longitudii'ial truss 11, transverse trusses 15 are provided adjacent to the front and rear ends of the longitudinal truss 11, said lateral trusses also forming additional supports for the hood 12, the latter forming a protective covering for the air compressing mechanism to be described.

Each shaft 4 carries a crossheud 16 which is connected at its oppositeends to a pair of piston rods 17 the pistons of which work in upper and lower air compressin cylinders 18 and 19 respectively, the cylim ers 18 and 19 bein arranged in vertical alinement with each ot er and there being two sets of pistons and cylinders for each shaft 4 although it will be understood that when desired any number of pistons and cylinders may be associated with one shaft 4 in accordance with the desii'eof the manufacturer and the particular use to which thomotor as a whole is put.

movements thus removing any lateral or I or collar 23 on the shaft 4. Adjacent to its twisting strain from the piston rods 17.

The shaft 4: is provided below the truss 11 with a cushioning spring 22 which is confined between said truss and'a fixed'shoulder upper end the shaft l is provided with another collar or shoulder 24: beneath which is a coiledcushioning spring 25 adapted to come in contact withthe top of the truss 11 when the shaft 4 approaches the lower limit of its movement. The springs 22 and 25 thus cushion the extreme movements of the shaft 4' and avoid an sudden impact between the shaft l-and the truss 11, therebyadding tothe smoothness of operation and durability of the mechanism involved. a

- Extending from each of the air compressing' cylinders 18 and 19 is a pipe or tube 26 leading into a common tank or reservoir 27 fsothat the air compressed in all of the cylinders is transferred to the common tank or reservoir 27. Extending outwardly from theitaiik 27 isa delivery nozzle 28 to which 'afiexible pipe or hose 29 may be attached to 'conveythe compressed air to the shore or point of use. -Whenthe :wave motor isanchored as shown in Fig. 1 so as to be subjected to a fore and aftrocking movement by the waves",

'the' duplex pistons will have a reciprocatory movement imparted thereto by reason of "their being submerged inja solid body of waterpthis eiiect beinlg materially enhanced by reason-oi the particular arrangement of the piston headsb and 6. "On account of the "'concave'sidesot-the pistons being arranged away from each other, there will be a c0n- :k siderable tendencyi'or said pistons to resist imparted to each ofthe shafts a.

"being drawn upwardor pushed downward bythe rising and falling member '1 and consequently a reciprocatory movement will be in the downward movement of one or the duplex pi'stonathe water will be trapped the concaveside of the lower piston head and will" slide'easily old the convex side of the upper piston-head while in he upward Arranged at opposite sidesof each shaft oi he obtained for five Washington,

movement of the duplex piston, the water will be trapped in the concave side of the upper piston "head and will slide freely oft the convex side of the lower piston head. This provides the necessary resistance to the movement of the duplex piston to efiect the reciprocation of the shaft. 4; which as previously noted-produces the reciprocatory movement of the piston rods 17 and the air compressing pistons in the "cylinders 18 and 19. w I

The motor as a whole, after being anchored. requires no attention 'on the part of the operator except the periodical lubrication of the working parts of the mechanism.

30 designates additional supporting posts for the longitudinal truss 11, and 31 inclined braces extending from the truss 1-1 and upper ends of the posts 30 downwardly to the deck 13 to which they are fastened.

"What i claim is 1-. in a wave'mot'or,- a portable buoyant member adapted to be anchored in a body of water, an air compressor carriedby said buoyant member, a normally vertical reciprocatory shaft for operating said air compressor, and asubmergedduplexpiston on said shaft, said piston comprising reversely disposed I PiSilOndlQtLClS concavo convex in cross section and having their convex surfaces facing each other.

a 2. in a wave motor, a portable buoyant member adapted to be anchored in a body of Water, an air compressor carried by said buoyant member, a normally vertical reciprocatory shaftfor operating said compressor, a submerged piston on said shaft embodying reversely disposed concave convex piston heads having their'convex sides facing each other, and anair'tight compartment interposed between the-piston heads.

in awave motor, a portable buoyant member adapted to be anchored in a body of water, an air compressor mounted thereon and embodying an air cylinder and piston and a normally-vertical reciprocatory piston shaft, a submerged piston operated by the resistance of the water in which said piston is submerged forimparting move-.-

ment to the air compressor, and means for yieldingly supporting and cushioning said cylinder. a In testimony whereof I aflix my signature in presence of two witnesses.
